To evaluate the clinical efficacy of ciprofloxacin (CFX) on treatment of the pigs with respiratory diseases or diarrhea. CFX at various dosages were administered intramuscularly to the diseased pigs selected from the pig farms located in Chungnam province. One hundreds and fourteen heads of pigs with respiratory diseases were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were found 31.8%, 73.9%, 91.3% and 92.0%, respectively, being higher than that of the untreated control group (19.0%). The mortality of the treated groups were 0%, that is lower than that of the control (9.5%). Seven kinds of bacteria were isolated from the respiratory organs of 86 pigs, and 34 (39.5%) of 86 pigs showed the complicated infection. In analyzing by the pigs infected with a single pathogen as P. multocida; A. pleuropneumonia. Staphyloccus spp. or Mymplasma spp., the recovery rates were 0∼66.6% at 0.25 dose, 66.6∼100% at 0.5 dose and 100% in all of 4 pathogens at 1.0 to 2.0 doses. At 0.25 dosage the pigs infected with A. pleuropneumonia showed the lowest recovery rate. One hundreds and twenty two heads of pigs with diarrhea were divided into five groups and CFX at 0.25, 0.5, 1.0 (= 2.5mg CFX/Kg B.W.) and 2.0 doses were administered i.m. for 5 days. The recovery rates were 29.1 %, 40.0%, 80.0% and 88.0%, respectively. The mortality of the treated groups were 0∼8.3%, being much lower than that of the control. Four kinds of bacteria were isolated from the fecal specimens of 94 pigs, and 84 (89.0%) of 94 pigs showed the complicated infection.

Apo B-100 is a constitutive component of low density lipoprotein (LDL) of which functions in packaging, transport, and absorption of lipids. Extortive binding of anti B4-antibody onto Apo B-100 should inhibited the functions of Apo B-100. Previously, we had showed that the peptide B4 induced antibodies recognized Apo B-100 and thus elicited anti-obesity effect. In this study, we compared the efficacy of peptide vaccine against obesity and of antibody inducing immune response by introducing additional peptides fused to B₄ Peptide. Previously, we had constructed B₄T, introducing additional peptides fused to the C-terminal of B₄ peptide, and BTB, fused to the middle of B₄ peptide, with preS2 of HBV. Then we manufactured vaccines, and vaccinated on C57BL/6 mouse. We measured weight of mice 3 days a week and, after vaccinating, we gathered blood and performed ELISA in interval 2 weeks for indicating antibody inducing immune response. Among these two artificial vaccines, B₄T was better Vaccine against obesity than another. But BTB was batter efficient inducer of the antibody against B₄. These result explains that B₄ tetramer is very crucial structural factor to operate as an obesity vaccine. Apo B-100은 low-density lipoprotein의 구성 요소로서 지방의 패키징, 운송, 흡수를 담당한다. App B-100에 anti B4-antibody의 인위적 결합은 이러한 Apo B-100의 기능을 저해할 것이다. 선행 연구에서 B4 펩티드에 의해 유도된 antibody가 Apo B-100을 인지하고 그에 따라 비만억제 효과를 나타내는 것을 확인하였다. 본 연구는 비만에 대한 B cell epitope을 4번 반복한 B4 펩티드에 추가적인 펩티드를 연결한 두 가지의 백신을 사용하여 효능을 비교하였다. HBV의 preS2를 B4의 C-terminal에 연결한 B₄T와 중간에 삽입시킨 BTB를 제조하여 C57BL/6 마우스에 주사하였다. 일주일에 3회 마우스의 체중을 측정하였고, 백신 주사는 2주 간격으로 4회 실시하였으며, 백신 주사 후 2주 간격으로 혈액을 채취하여 면역 반응에 의해 유도된 antibody를 indirect Enzyme -Linked Immunosorbent Assay에 의해 측정하였다. 두 가지 백신 사이에서 체중 증가 억제율로 본 비만에 대한 백신효과는 B₄T가 더 우수하였다. 그러나 B₄T에 비해 BTB가 유도된 antibody의 titer와 혈중 지속 시간이 더 우수했다. 이런 결과는 B펩티드가 항체유도에 있어서 중요하지만, 비만억제 기능에 있어서 B₄ tetramer가 매우 중요한 인자임을 입증하였다.

β-glucan occuring mainly in mushrooms and fungi are attractive candidates for numerous industrial application due to their pharmacological activity such as antitumor activity via immunomodulating behavior and excellent rheological properties such as emulsification, viscosity, jellation, etc. Screening of β-glucan producing microorganism was performed by congo red dye binding assay of ethanol-precipitates from each culture filtrate. The β-glucan produced form the selected strains was purified mainly by directly diluting the culture broth with the same volume of water, removal of cells by centrifugation at 4,000×g for 20 mim, and precipitation with 3 volumes of ethanol. The monosaccharide composition was analyzed by either TLC or HPLC afer trifuoroacetic acid hydrolysis. The molecular mass of the β-glucan of HH-71 strain was estimated to be about 4,500,000 dalton on a GFC-HPLC chromatogram. A Bacillus protease coated with β-glucan showed 3-times more increased thermal stability comparing to the uncoated control when stored at 30℃ for 1 week. In a similar manner coating of wastewater (containing chlorinated organic compounds) treatment bacteria with β-glucan resulted in significant increase of thermal stability. Although more detailed experimental data need to be accumulated, these preliminary data clearly suggest that β-glucan is applicable as a coating material to stabilize activity or viability of industrial enzymes and microorganisms for treatment of wastewater. Based on these results, β-glucans obtained from HH-71 and HH-87 strains are currently investigated for coating ablility of microbial consortia for the treatment of wastewater.

The affective factors on regional anesthesia are lipophilic-hydrophilic balance of local anesthetics, protein binding, hydrogen concentration, structure of intermediate chain, and etc. Local anesthetics in solution exit in a chemical equilibrium between the basic uncharged form(B) and the charged cationic form(BH^+) by Henderson-Hasselbalch equation(PH_a=PK+log[B]/(BH^+)). The increasement of uncharged form brig about rapid onset, good quality, and long duration of anesthesia. Eight patients in group Ⅰ were given 2% lidocaine 21.7ml with 1: 200,000 epinephrine(pH 5.1), and eight patients in group Ⅱ were given 2% lidocaine 20ml with 1: 200,000 epinephrine added NaHCO_3 1.7ml(pH 7.2) to determine the epidural analgesic effect of the pH-adjusted solution. The results are summerized as follow 1. The onsets of analgesia and surgical anesthesia were significantly rapid in group Ⅱ. 2. The levels of analgesia were raised more rapidly in group.

연구목적: 여성 요도증후군을 보이는 환자에서 교감신경차단제인 terazocin을 복용한 후 치료 효과에 대한 각 증상의 변화와 부작용을 알아보고자 하였다. 대상 및 방법: 1997년부터 1999년까지 충북대학교병원 비뇨기과에 내원한 35명의 여성 중 요검사 및 요배양 검사, 그리고 다른 이학적 검사에서 이상이 없는 요도증후군 환자를 대상으로 간질성방광염 증상점수(ICSS)를 terazocin (3mg/day for 3 months) 투여 전후에 조사하였고, 치료 후 3개월과 1년에 Likert scale 점수를 조사하였다. 결과: ICSS는 비치료군은 18.3±5.9점, 치료군은 16.5±6.8점으로 두군간의 차이는 없는 것으로 나타났다(p=0.52). 치료군은 치료 후 3개월에 시행한 ICSS가 9.9±7.8점으로 치료 전에 비해 현격히 증상이 호전되는 것으로 나타났다(p=0.0001). 특히 3개월에 시행한 Likert scale에서는 주간 및 야간빈뇨, 절박뇨, 배뇨통의 횟수 및 강도, 그리고 전체적인 증상정도에서 40-70% 가량 호전된 것으로 밝혀졌으며 이는 1년 후에도 증상의 호전이 지속되는 것으로 나타났다. 비치료군에서의 1년 후 Likert scale은 6명 중 2명이 전체적인 증상의 호전이 있는 것으로 나타났다. 결론: Terazocin은 환자의 약 70%가량에서 증상의 호전을 가져왔고, 비치료군에서도 환자의 33%가 저절로 증상이 좋아진 것으로 보아 Terazocin은 여성 요도증후군에서 분명히 효과가 있으나 증상이 심할 경우 보조적인 치료로 이용되는 것이 바람직할 것으로 사료된다. Purpose: We performed to assess the effects and complications of terazocin in women with chronic female urethral syndrome. Materials and Methods : Thirty-five women with chronic female urethral syndrome were studied from March 1997 to August 1999. The subjects exhibited normal findings without the pyuria and bacteriuria in urinalysis and urine culture and were invested the interstitial symptom score(ICSS). 29 subjects of them took a terazocin 1-4 mg/day for 3 months. They were reevaluated for the ICSS and Likert scale after 3 months and for Likert scale after 1 year. Results: The ICSS before treatment were showed 18.3±5.9 in the untreated patient group and 16.5±6.8 in the treated patient group, and no statistically difference between both patient groups(p=0.52). In the treated patient group, the ICSS after treatment were showed 9.9±7.8, significant difference between before and after treatment(p=0.0001). The Likert scale was showed at 3 months after treatment that frequency, nocturia, urgency, pain frequency, pain intensity, daily activities, and overall symptoms were improved in 65.5%, 55.2%, 24.1%, 41.4%, 41.4%, 70%, 70%, and 70% of 29 subjects, each other. Overall symptom score assessed at 1 year were showed that 3 subjects was aggravated. In untreated patient group, 2 of 6 was improved in overall symptom score. Conclusion: Terazocin was effective above 70% in the treated group, and symptoms were improved spontaneously in a third of the untreated group. So, we thought that terazocin would be useful as supportive treatment in period of severe symptoms.

The proliferation of the internet and related applications has made users struggle with information overload. It means users must spend more time to find and gather necessary information they want. The agent technique is advocated by many researchers as an alternative to overcome the difficulty, which resulted in the practical use of the agent technique in Electronic Commerce more common. In this paper, we propose a realtime price comparison agent which compares the prices and services among online stores in realtime without users' intervention. The proposed agent differs from the existing ones in that (1) it does not incorporate a pre-installed price database, (2) it automatically monitors users' current status without any input from the users.

연구목적: 뇌파의 시공간적 패턴분석(spatio-temporal pattern analysis)방법을 이용하여 알쯔하이머형 치매의 진단 특히 초기 치매환자의 진단에 대한 예비연구를 하고자 하였다. 방법: 알쯔하이머형 치매환자 10명과 정상대조군 10명을 대상으로 하여 Karhunen-Loeve 분해법을 이용한 시공간적 패턴분석을 통하여 비교하였다. 결과: 첫째, 세가지 주요패턴 중 가장 많은 빈도를 보인 으뜸패턴에서 알쯔하이머형 치매환자는 좌우측 비대 칭성이 정상대조군에 비해 뚜렷해지는 형태를 보였다. 둘째, 으뜸패턴을 비교하여 뇌의 각 부분에 대한 차이를 보았을 때 알쯔하이머형 치매환자는 대조군에 비해 주로 좌측 두정부와 측두엽 부위에서 고유값의 유의한 차이가 있었다. 셋째, 으뜸패턴 전개계수의 Fourier amplitued spectrum 분석을 통하여 알쯔하이머형 치매환자 10명중 6명에서 상당히 큰 진폭의 상승부분을 관찰할 수 있었으며 정상대조군에서는 이러한 진폭의 이상소견이 관찰되지 않았다. 결론: 본 연구의 결과는 알쯔하이머형 치매으 병태생리적 위치가 좌측 측두-두정엽에 있음을 시사하였으며 앞으로 시공간적 패턴분석 방법이 알쯔하이머형 치매환자의 진단에 유용하게 사용될 수 있도록 추후연구가 필요할 것으로 생각하였다. Objectives: We introduce a novel analysis method of spatio-temporal pattern analysis of EEG. Using it, we presents a results discriminating severe Alzheimer's disease patients from normal subjects. Methods: To the groups of 10 Alzheimer's disease patients and 10 normal aged subjects, we applied the Karhunen-Loeve decomposition method and observed their principal patterns and time-varying dynamics. Results: First, there was a first primaty pattern of the eigenvector in Alzheimer's disease patients that showed opposite polarities at the left and the right hemispheric regions. Second, the Alzheimer's disease patients had significantly different average values of the eigenvector at the left parieto-temporal area than the normal controls did. Third, some Alzheimer's disease patients had one, coherent frequency component in the Fourier amplitude spectrum of the first pattern expansion coefficient. Conclusions: Our results suggest that the pathophysiologic site of Alzheimer's dementia may be left temporo-parietal area in brain and further studies need to evaluate whether the spatio-temoral pattern analysis could be used to diagnose Alzheimer's dementia patients.
